Could I get some specific recommendations for a bike for a 7 year old?
Price limit is say 150 US dollars.
What is best for brakes (front hand + back foot vs. just hand)?
Should I go for one-speed or 3 or 7?
Should I go for 24 inches vs. 20 inch (He's now 48 inches tall)
I would like him to use it for awhile, if possible, best fit and good experience for him would be more important I guess.
